1.	The degree of protection of a lyophobic colloid by the addition of a lyophilic colloid is measured in terms of :A. Gold numberB. Coagulation valueC. SedimentationD. None of these
Answer» Correct Answer - A Gold number is the amount of lyophilic in mg which just protect 10 mL gold sol against coagulation by 1 mL of 10% NaCl solution. It is a measure of protectivey power of lyophilic colloid.
